Q: How do you remove and install the CKP sensor in a Buick Enclave,Chevrolet Traverse and GMC Acadia?
A: Raise the front of the vehicle and support it securely on jackstands. Remove the heal shield covering the wiring harness and sensor. Disconnect the electrical connector from the CKP sensor, which is located at the rear of the engine block on the firewall side. Unscrew the mounting fastener and remove the CKP sensor. Before installing the sensor, lubricate the O-ring with clean engine oil. Installation is otherwise the reverse of removal.
